摘要 光学谐振腔不仅可以增强激光和物质的相互作用,而且能够抑制激光的噪声,是开展精密测量、量子光学等研究的重要工具。激光和光学谐振腔共振的稳定锁定是其应用的关键。然而,在实际环境中锁定效果会受机械振动、温度变化等因素的影响。提出了将模糊算法应用于PDH(Pound-Drever-Hall)技术,使比例积分微分控制器的三个参数能够根据外界环境变化进行调节以实时获得最优参数,有效提升了光学谐振腔的锁定的抗干扰能力。如果外界干扰仍然过大以至于失锁,系统可以使其自动重新锁定。该系统有效增强了光学谐振腔的实用性,为光学谐振腔在精密测量、量子光学实验中的应用提供了技术基础。 The optical resonant cavity can not only enhance the interaction between the laser and matter,but also suppress the noise of the laser,which is an important tool for research on precision measurement,quantum optics,etc.Stable locking of laser and optical resonant cavity resonance is the key to its application.However,the locking effect will be affected by factors such as mechanical vibration,temperature changes,etc in the actual environment.The fuzzy algorithm is applied to the PDH(Pound-Drever-Hall)technology,so that the three parameters of the proportional-integral-differential controller can be adjusted according to the changes of the external environment to obtain the optimal parameters in real time,which effectively improves anti-interference ability of optical resonator locking.If outside interference is still so great that the lock is lost,the system can make it re-lock automatically.The system effectively improves the practicality of the optical resonator,and provides a technical basis for the application of the optical resonator in precision measurement and quantum optics experiments.
